IMPROVEMENT IN STRAW-GUTTERS.

r0 WHOM IT MAY CONCERN:

Be it known that I, IV-ILLIAM I'I. EVANS, of Richmond, Indiana, haveinvented certain new and useful improvements in Straw-Cutters; and I dohereby declare the following to be a full, clear, and exact descriptionof the same, reference being had to the accompanying drawings, and tothe letters of reference marked thereon, in 'which- Figure 1 is a.perspective view of my improvement; and

Figure 2 a sectional bottom view of the same. I i

A represents the framing of the box of a straW-cutter'of the usual form,and B is an ordinary balancewheel attached to and turning upon the shaftC, while D is an eccentric plate-wheel placed upon and revolving withthe shaft C inside of the balance-wheel B. E is a rock-shaft, the lowerend of which is hinged near the bottom of the front upright post of theframing, being vertical, and extending above the line of the shaft C. Atthe top of the rock-shaft E is attached at right angles an arm, F, theopposite end of which is provided with a slot, which slot works upon thejournal of the ratchet-wheel J, which serves as a guide and support forthe same. The spring L, attached to the ear M at one end, and to-therock-shaft'E at its opposite end, serves to hold the rock-shaft firmlyagainst the face of the eccentric-Wheel D. Attached to the horizontalarm E are pawls 1 and 2 "arranged to operate the ratchet-wheels J and K,which are on the outer ends of the feed-rollers of the straw-cutter. Itwill be seen that by a mul et the shaft C the eccentric D carries therock-shaft back, producing a reciprocating motion of the arm F andpawl-s l and 2,'and producing a. partial revolution of the feed-rollersby means of the ratchet-wheels J and K. G is an adjustable stop operatedby the lever H, fig. 2, and attached to the bottom of the straw-box, bywhich the amount of vibration is controlled, and length of the fodderout regulated at will, and while the machine is in motion. The rack I,fig. 2, attached to the bottom of the straw-box, is arranged with aseries of stops to hold the lever H in place, as may be desired.

Having thus fully described my said improvement, what I claim, as myinvention, and desire to secure by Letters Patent, is-

1. The rock-shaft E, slotted arm F, pawls 1 and 2, and spring L, incombination with the eccentric-wheel D and feed-roller ratchets J and K,arranged and operating substantially as herein set forth and described.

2. The stop G, arm or lever II, and rack I, in combination with therock-shaft E, as and for the purposes set forth.
